2022, May 31st rmac 2.2.2 relesed. Changes since last release:

  • ds directive now works with expressions that have undefined symbols (as long as they are resolved by the end of assembling)
  • equr has been overhauled and now works with all target architectures
  • Label names clashing with register names is now restricted to target architecture register names. As an example, this means that a label name of “a:” is now illegal only if the selected architecture has a register name “a” (at the time of writing: DSP56001 and 6502)
  • Printing a listing with -l* now doesn’t print \f characters when printing the symbol table
  • Register and Condition Code equates are now not exported as symbols

2022, May 11th There now exists syntax highlighting support for the editor 10x. If you have the editor installed, simply download rmac.10x_syntax and place it in your %APPDATA%\roaming\10x\Settings\SyntaxHighlighting folder. By default it works for .s files but it can be easily changed to support other extensions as well
